PUMP ATTACHMENT FOR OIL-CANS.

SPECIFICATION forming part of Letters Patent No. 275,883, dated April 17, 1883u Application filed April 18, 1882.

1'0 all whom it may concern:

Be it known that I, MATTHEW BURTON, of Batavia, in the county ot' Kane and State ot' Illinois, have invented certain new and useful Improvements in Pump Attachments for Oil- Cans; and I do hereby declare that the followin g is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specidcation.

My improvements relate mainly to a special construction of pumping apparatus for attachment to and removal from oil-cans, the construction being such that by the unscrewing of a single screw plug, or cap from a threaded opening in the top of the can and lifting out such plug it will also remove the pump-cylinder, its piston, piston-rod, and valves, and the ejection-pipe, and also the screw plug or cap ot' the cylinder, all of which are connected together, as will now be described.

Figure l represents my invention complete, ready to be inserted into any appropriate small threaded opening in a can; Fig. 2, an Voil-can with my. pumping apparatus applied thereto, and Fig. 3 one of the valves in detail.

A is the screw-threaded cap or plug, to which is secured the cylinder or piston tube B and the discharging-tube C, and the cylinder-cap D, piston or plunger E, and the valves ff are Aalso sustained by the same cap, A, and all these parts are applied to and may be removed from the can at one act by simply screwing or unscrewing this cap A.

The can itself may be of any form of construction desired, and its entire top may be permanently covered, except the opening for the cap A, and it may be provided with a safety-trap, g, for the purpose of llin g the can and preventing the escape of the gas. By unscrewing the cylindercap D the piston E can be taken out for repairing, Src., without disturbing any other part.v

The valves f f are placed one on the inside of the tube B and one on its outside, as shown, at the passage or outlet between such tube (No model.)

and the tube C. These valves are made of a piece of leather, preferably round in shape, and held or clamped firmly at one edge by a clip,h, made of tin. This tin is then soldered to the cylinder and the valve is complete, the solder holding it to place and the leather affording sutlicient flexibility to serve as a hinge.

The plunger or piston E is made by placing on the rod two circular plates or washers, t' fi', and two nuts, j j'. Over these washers is drawn a leather cap or cup, lc, and the lower nut, being applied, holds it fast, as shown. Suitable rings or smaller washers, w, on the rod serve to separate the plates t' and t', and the nuts tighten these plates against the rings or washers. l f

By attaching the parts, as described, to the one cap or plug A these parts always preserve their proper relative positions, and, whether this cap be screwed down more or less, these relative positions are not thereby changed, though the positions of the tubes B and C relatively to the side of the can will be changed according to the extent of the screwing.

In Fig. 2 the top 0f the can is shown as made with a surrounding rim and with an inclination, m', extending therefrom toward the central inlet and trap, g,- but in order that the pump shall stand or hang perpendicularly Wh en inserted in and applied to the can, an elevated or raised projection or nipple, l, is provided having a level or horizontal portion, m, on which the screw-cap A may rest when the cap is screwed to its place on this threaded projection. The side or wall a ot' this raised or higher portion l may be perpendicular.

The stand for holding temporarily a lamp to be filled may be placed upon the inclined surface of the can.

I claiml. In an oil-can having a permanent top or cover provided with a threaded raised nipple, l, surrounding a small opening made near one side of said cover, the small threaded cap A, combined with and adapted to be screwed upon such nipple, and permanently secured to and supporting both the force-pump B and its discharge-tube C, both of which project through f 275,883 l i :t i it into the can, and whereby they are both reand having the tube B and tube C perma- W( movable from the can by the unscrewing of nently axed to and projecting through sucn this cap, all as shown and described. cap, all as and for the purposes set forth.

2. In combination with an oil-can having' a MATTHEW BURTON. 5 permanent top, made with theincline m', raised Witnesses:

part m, and its threaded nipple l, as set forth, JOSEPH BURTON, the threaded cap A, adapted for sueh nipple, i THOMAS BASKERFIELD.
